The values for header elements requiring measurements are expressed as thermal dots or
pixels. Dot or pixel size varies depending upon the print resolution of the print head. The
dot size of a 300 dots per inch head (12 dots/mm) is 0.0033”. The dot size is the same in
both the horizontal and vertical direction. For example, a 4” X 6” label printed with a 300
DPI print head would be 1200 (4 X 300 dots in the horizontal or “X” direction, and 1800 (6 X
300) dots in the “Y” direction.
While the maximum number of dots in the horizontal or “X” direction is limited by print head
size, it is virtually unlimited in the vertical or “Y” direction. Vertical dot rows are “stepped” by
the drive roller motor.
